Anton Gerner Furniture in Australia has built a simple wood version of my resaw jig. The jig is made out of wood scraps, cheap wheels and 2 trampoline springs providing pressure right where it is needed. The springs ensures your material stays tight to the fence even when there is a slight variation in material thickness. The function is very similar to a professional resaw with the exception that you are feeding the material by hand.
A bandsaw is the first choice for resawing with this jig but you can use a table saw if you are careful. Resawing on a table saw usually requires 2 passes because of the limited blade height and the tremendous power required with so many saw teeth cutting. To do this you raise the blade just enough to cut halfway through the board on your first pass. With the first pass complete, flip your material, disengage the top roller, and finish your cut with a second pass. If you are going to use this method it is IMPORTANT that you disengage the top roller for the second pass or the top wheel will be pressing on the empty kerf from the first cut. This will both scar the material and potentially pitch the spinning blade.
